Blue Sea 7428 Single Pole Small Case 2" Slot Reset Rocker Circuit Breaker - 15 Amp

The Blue Sea 7428 Single Pole Small Case 2" Slot Reset Rocker Circuit Breaker is a 15 Amp electrical protection device engineered for marine, automotive, and industrial applications where reliable overcurrent protection is essential. This compact breaker is designed to safeguard sensitive electrical systems by interrupting power when amperage exceeds safe limits, preventing equipment damage and fire hazards. Whether you're upgrading a boat's electrical panel, securing an RV power distribution system, or protecting auxiliary circuits in a vehicle or industrial equipment, this small-case breaker delivers dependable performance in demanding environments.

Built by Blue Sea Systems—a leader in marine electrical safety—this single-pole breaker features a trip-free design that ensures the breaker cannot be held in the ON position if an overcurrent condition exists. The rocker actuator clearly indicates OFF position through color differentiation, providing instant visual confirmation of breaker status even in low-light conditions. The 2-inch slot configuration allows seamless integration into standard Blue Sea Systems panelboards and compatible electrical enclosures, while the robust construction withstands vibration, salt spray, and temperature fluctuations typical of marine and mobile applications. At just 0.15 lbs and measuring 2 x 1 x 3 inches, the compact footprint maximizes panel real estate without sacrificing current-handling capacity.

This 15 Amp breaker is ideal for protecting individual branch circuits serving navigation lights, cabin lighting, bilge pumps, auxiliary systems, or any moderate-load circuit requiring reliable automatic disconnect. Marine electricians, RV technicians, and automotive specialists rely on Blue Sea breakers for Class T and traditional panel upgrades where safety codes demand trip-free operation and visual status indication. Installation requires a compatible 2-inch slot panelboard; verify your enclosure's slot configuration and spacing before ordering. For systems demanding redundancy or higher amperage protection, consider pairing multiple breakers across your panel distribution strategy.
